GS4A0361R9GCT Description

The GS4A0361R9GCT from TT Electronics/IRC is a high-precision 4-resistor isolated network in an 8-pin narrow SOIC package, designed for demanding surface-mount applications. Featuring a 61.9Ω resistance value with a tight ±2% absolute tolerance and an exceptional ±0.25% ratio tolerance, this ceramic-based thin-film resistor network ensures reliable performance in precision circuits. Its ±25ppm/°C temperature coefficient and 100V maximum voltage rating make it suitable for stable operation across a 70°C to 125°C derated power range. The SOIC-C series construction offers robust 0.1W power dissipation per resistor (0.4W total), with a compact 4.9mm × 5.99mm × 1.45mm footprint and gull-wing termination for secure PCB mounting.
